UNITED STATES JOHN ROMSTEAD, OF SEATTLE, WASHINGTON.

- WATER-HEATER FOR GAS-STOVES.

Application filed. September 13, 1919.

To all whom it may concern.

Be it known that I, JOHN RoMs'rnAD, a citizen of the United States,residing at Seattle, in the county of King and State of Washington, haveinvented a certain new and useful Improvement in Water-Heaters forGas-Stoves, of which the following is a specification.

My invention relates to improvements in water heaters for gas burningstoves and the object of my invention is to provide a water heater inthe form of a water coil that may be arranged within the oven of a gasburning stove in such a manner as to be out of the way and to utilizethe heat of the baking and broiling ovens to the best advantage to heatwater, thereby doing away with the necessity of a separate water heaterof the type commonly used where gas stoves are employed.

A further object is to provide a coil that is easy to install and thatis especially adapted for use with the type of oven burners common toordinary gas burning stoves.

The invention consists in the novel construction of a water heating coiland the adaptation and combination of such coil with an ordinary gasburning stove as will be more clearly hereinafter described and claimed.

In the accompanying drawings Figure 1 is a view in verticalcross-section, substantially on a broken line 1, 1 of Fig. 2, of an ovenhaving my water heating apparatus installed therein, and

Fig. 2 is a view in cross-section of the same, substantially on a brokenline 2, 2 of Fig. 1, the water heating coil and burner pipes being shownin plan.

Like reference numerals designate like parts throughout the drawings.

Referring to the drawings the numeral 5 designates a baking oven and 6designates a broiling oven that is separated from the baking oven by apartition wall 7 and is provided. with four transversely arrangedparallel burner pipes 8, 9, 10 and 11 that communicate with a gas inletpipe 11.

The burner pipes 8, 9, 10 and 11 are spaced below the partition wall 7,as shown in Fig. 1, and two alternate burner pipes, as the pipes 9 and11, are perforated on their upper sides for directing divergent jets ofupwardly against the partition wall 7, while the two other burner pipes8 and10 are perforated on their lower sides Specification of LettersPatent.

Serial No. 323,659.

for directing divergent jets of gas downwardly into the broiling oven 6.

,The perforations in each pipe are preferably arranged in two rows, asshown, and are arranged todirect the gas outwardly in divergent jets.

The water heating coil comprises four straight sections of water pipes12, 13, 14 and 15 that extend crosswise of the oven and parallel withthe burner pipes and are connected with each other by shorter sections16, 17 and 18.

The pipes 12 and 15 are connected with other pipes 20 and 21,respectively, that are arranged to project outwardly and may beconnected in the usual manner with a hot water storage tank, not shown.

The coil is preferably formed so that all of the pipes lie in the sameplane and such coil is supported in the space between the partition wall7 and the burner pipes 8, 9, 10 and 11, the water pipes 14 and 15 beingspaced just far enough to be directly in the path of the divergent jetsof gas that are emitted from the burner pipe 11, and the pipes 12 and 13being similarly arranged and disposed with respect to the burner pipe 9.

The ovens may be of any standard form of construction and may beprovided with doors 22 of the usual type.

When arranged in the manner shown and described, the water coil willalways be subject tothe heat from the oven burners when the latter arelighted and will serve to heat water without detracting materially fromthe efficiency of the oven.

The water pipes being located directly in the path of the gas jets thatare emitted from the burner pipes will always be in the most highlyheated area of the oven and will serve as deflectors to spread the flamefrom the burners before it strikes the bottom wall 7 of the oven 5.

In practice the water coil may be formed,

of a single pipe bent into the shape shown or it may be made of aplurality of short sections of pipe connected with each other by elbowfittings in a Well known manner.

My water heating coil occupies space that is not available for any usein the oven and is very quickly and easily installed by cutting holes inthe rear wall of the broiling oven and then inserting the made up coilthrough the oven door and making the necessary pipe connections.

Obviously, changes may be made in the forms, dimensions and arrangementof parts of my invention without departing from the spirit thereof.

hat I claim is:

In an apparatus of the class described, the combination with a bakingoven, of a broiling oven disposed below said baking oven and separatedtherefrom by a partition wall that serves as a bottom wall for saidbaking oven and a top wall for said broiling oven, a plurality of burnerpipes eXtending crosswise of said broiling oven and spaced below saidpartition wall, certain of said burner pipes being arranged to directjets of gas upwardly toward said partition wall while other burner pipesdirect jets of gas downwardly, and a continuous water heating coilsupported between said partition wall and said burner pipes, said watercoil having inlet and outlet pipes that project outwardly through therear wall of'said broiling oven and being provided with water heatingpipes that are arranged in pairs with each pair spaced slightly abovethe burner pipes having the upwardly directed nozzles and the pipes ofeach pair at opposite sides of the burner pipe in proximity thereto andsubstantially parallel to said burner pipes and are disposed in the pathof the gas jets that are directed upwardly from said burner pipes.

In witness whereof, I hereunto subscribe my name this 6th day ofSeptember A. D.

JOHN ROM STEAD.
